To find the area of each family garden, we first calculate the area of one garden by multiplying its dimensions.
Each family garden has dimensions of \(1.3\) miles by \(3\) miles:
\[ \text{Area of one garden} = 1.3 , \text{miles} \times 3 , \text{miles} = 3.9 , \text{square miles} \]
Each garden has an area of \(3.9\) square miles.
Next, to understand how many gardens can fit in the overall field of \(3.9\) square miles, we would divide the total area by the area of one garden:
\[ \text{Number of gardens} = \frac{\text{Total area}}{\text{Area of one garden}} = \frac{3.9 , \text{square miles}}{3.9 , \text{square miles}} = 1 \]
Thus, you can fit 1 garden of \(3.9\) square miles in a \(3.9\) square mile field.
